Technology of the Process
Process technology information is a part of the process safety information package and should include employer-established criteria for:
- maximum inventory levels for process chemicals;
- limits beyond which would be considered upset conditions; and
- a qualitative estimate of the consequences or results of deviation that could occur if operating beyond the established process limits.
Information on the technology of the process must include at least the following:
- A block flow diagram or simplified process flow diagram,
- Process chemistry,
- Maximum intended inventory,
- Safe upper and lower limits for such items as temperatures, pressures, flows or compositions, and
- An evaluation of the consequences of deviations, including those affecting the safety and health of employees.
Where the original technical information no longer exists, information may be developed in conjunction with the process hazard analysis in sufficient detail to support the analysis.
Note: Safety Data Sheets (SDSs) meeting the requirements of the Hazard Communication Standard (20 CFR 1910.1200) may be used to comply with this requirement to the extent they contain the required information.
